To make the chicken, place a chicken breast between two layers of cling film and lightly bash with a rolling pin or meat hammer. When flattened to a centimetre in thickness season with salt and pepper. Heat a large griddle pan over a medium high heat. Griddle the chicken breasts for 7-8 minutes on either side until cooked through. Set aside to cool, or chill, if preferred.
For the croutons, pre-heat the oven to 200c. Lightly tear the ciabatta into rough chunks and toss into a bowl with the olive oil, salt, pepper, rosemary, and garlic. Mix everything together so the ciabatta is evenly coated. Line a baking tray with parchment and lay the uncooked Croutons in a single layer. Bake the croutons in the centre of a preheated oven. Cook for 8-10 minutes until golden brown. Then, turn the croutons, and bake again for another 8-10minites.
For the dressing, pound the garlic, and anchovies with a pestle and mortar until a paste forms. Combine with the other ingredients and season to taste. The Dressing may be quite thick so add a splash of water to reach the desired consistency.
Bring a pan of water to the boil and cook the eggs for 4-6 minutes for a soft to medium boiled egg.
Heat a griddle pan and grill the bacon until crispy.
To build the salad, toss the leaves with the dressing. Top the salad with there other finishing ingredients and serve.
